JACOB MA RX, OF XEYV YORK, N. Y.

REFRIGERATOR.

Specification of Letters Patent No. 23,478, dated April 5, 1859.

To all whom it may concern:

Be it known that I, JACOB MARX, of the city, county, and State of New York, have invented new and useful Improvements in Refrigerators; and l do hereby declare that the following is a full, clear, and eXact de- I scription of my invention and ot its appliw cation, reference being had to the annexed drawings, making part of this specification, in which- Figure l, is a perspective view of the refrigerator; liig. 2. a cross section ot the refrigerator; Fig. 3, a top view of the ice chamber; Fig. Zl, a longitudinal section of the ice chamber; Fig. 5, a perspective view ot' the cross-section of the ice chamber.-

Similar letters of reference indicate corresponding parts in these various figures.

I deem it proper to state, that the refrigerators, at present in use, are either devoid of any regular communication between the provision chamber and the exterior atmosphere, or where such communication is provided for, the draft passes through the ice chamber, thereby causing a material increase in the consumption of ice, requisite to maintain a cool temperature. Moreover of air, one current passing from the iceis collected in a vessel separate from and independent of the refrigerator. In my refrigerator I have obviated these defects, by making the water tank part of the refrigerator, and by causing a double circulation of air, one current passing from the ice chamber to the provision chamber, and the other from the provision chamber to the est- A terior air. This latter communication is especially desirable in all cases, where the vapors of the provision chamber are to be carried ofi".

The nature of my invention consists, in providing the refrigerator with a drawer in which the ice water collects; in constructing the ice chamber with a double front piece and a corrugated bottom, and the provision chamber with internal openings; for the purpose of eifecting a double circulation ot air, or ventilation, as will be hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

My refrigerator consists of an ice chamber A, a provision chamber B, and a water tank C. The ice chamber is made to form a drawer, and is so placed in the upper part of the refrigerator, that it may be drawn in, or out at pleasure. It has a double front piece; the exterior front piece a being in the usual vertical position; the inner front piece c in a slanting position and a continuous open space being left between both.

The bottom of the ice chamber is made of corrugated sheet metal n, which is sup ported on the sides between two strips G G of similar sheet metal, and forms in the central line K L a groove or gutter D, from which a pipe E passes from the provision chamber into the water tank below. The provision chamber B below the ice chamber is made slanting on the top at s, and with apertures near the bottom said apertures eX- tending to the width of the water tank C. The said water tank is made to form a drawer capable of being opened or closed, by being drawn out or in.

lVlien ice is placed in the ice chamber, the cold air will descend into the provision chamber through the triangular spaces of the bottom of the ice chamber, as shown by the position of the arrows l and 2 in Fig. 5; and this interior ventilation will take place independent of the drawers A and C; that is to say, independent of their being opened or closed, and thus a uniform cool temperature of the provision chamber will be achieved. When it is desirable to eect a communication with the atmosphere, the water tank C and the ice chamber A are partially pulled out; the latter only so far, that interior front piece e still closes on the top or lid of the refrigerator, as shown in Fig. 2. The exterior air will then enter through the open water tank. It will then pass through the openings 'v into the provision chamber, and will escape through the open space at s, without passing through the ice chamber, as shown by the black arrows in Fig. 2. In this manner a communication with the exterior atmosphere is eifected Without thereby increasing the temperature Chamber A the gutter D, pipe the Water of the provision chamber. The red arrows tank C and provision chamber B substann Figs. 2 and 3 show the passage of the Watally as and for the purpose speced.
